When it’s pouring rain outside, the greenhouse is definitely the best place to be. It’s not exactly warm on a gray day and it’s not completely dry either but it is full of summer’s promise. Visitors can’t help asking if the plants are for sale. It’s a good question because I’d want them for my own garden too. But, alas, they are not for sale – at least not here. Everything in the greenhouse is destined for Blithewold’s gardens. We have some new plants that I’m especially excited about and just in case you might be too, here’s the scoop on where you can find them:

Avant Gardens is selling a new (it’s new to us – is it new to the world?) hummingbird mint – Agastache ‘Summer Glow’. If it glows anything like the picture on the tag I’m smitten and I don’t even love yellow. Those will go in the North Garden. They are also selling this adorable violet with pewter leaves (Viola walteri ‘Silver Gem’.) Anything that looks like jewelry really needs to be planted in the jewel box of our Rock Garden.

Annie’s Annuals, a mail order source on the other coast, is selling a hook sedge (Uncinia uncinata ‘Rubra’) that promises to turn garnet red in the garden. I suppose they should go in the Rock Garden too but I’ve had my eye on them for a necklace of containers. A speckled leaved honesty (Lunaria annua ‘Rosemary Verey’) from Annie’s will find a spot in the Display Garden and I hope-hope-hope it comes true from seed next year.

Dahlia ‘Kaili’, which came in exactly a month ago as a rooted cutting from Corralitos Gardens, another mail order source from California that specializes in the prettiest dahlias, is already fulfilling its promise. We can be certain that it, ‘Golden Cloud’, ‘Granville’, and ‘Bishop of York’ will be gorgeous planted in the North Garden.

With more and more people planting vegetables, they are easier and easier to find as starts at almost any nursery or farmer’s market. We grew these tomatoes from seed from several different sources including Baker Creek and Johnny’s. I can’t wait for my first Sungold snack…

Have you found plants you’re excited about this year? What are they, and where can we buy them?

Now that the heat of April is behind us, we’re taking full advantage of the coolness and rain of May. The weather is a little backwards but we’ll take what we can get when it comes to planting weather. With a few days of rain in the forecast we were really thrilled to have a dry day today and a good crew to start putting in some of our cool-season annuals. We planted tassel flower (Emilia javanica) in what promises to be a stunning combination with annual campion (Viscaria occulata ‘Blue Angel’). We also planted calendula, Salvia claryssa (a diminutive clary sage), some pretty tough looking bee’s friend (Phacelia tanacetifolia), golden feverfew (Tanacetum parthenium ‘Aureum’), Virginia stock (Malcolmia maritima), ornamental kale ‘Sunset’, and honeywort (Cerinthe major var. purpurescens ‘Kiwi Blue’) among other various and sundry things I’ve already forgotten.

In some places we had to elbow a few volunteers out of the way – volunteer reseeders, that is. You might this this sea of teasel seedlings is horrific but I like to think of them as a really excellent weed barrier. Nothing can penetrate that mat but it was quick work to delete a few to make room for a new little border of clary sage. And with any luck that will seed itself around too.

All of the garden’s newest tenants will be happy to have cloudy skies and plenty of rain (fingers crossed) to help them settle in. And now we have more room under the arbor for “hardening off” the next batch of plants to come out of the greenhouse. Tender perennials like Mexican anise hyssop (Agastache spp.), salvias, porterweed (Stachytarpheta spp.), and geraniums (Pelargonium) are next on the list — although all of those might prefer to wait to go out after the rain has stopped. That’s alright because it’s also time to move out some of our container specimen like the camellias, coprosmas, farfugium, and sweet olive (Osmanthus fragrans). The shift is on.

Have you started to plant cool-season annuals yet?

Word from our Visitor’s Center is that visitation drops off in May. I can’t imagine why. We might not be promoting daffodils anymore but there is still so much going on here. More and more every day. This week, after the Wednesday volunteer group (The Rockettes) planted the sweet peas along the cutting garden fence, a few of us went down to the Rock Garden. I think it’s safe to say that it has never looked sweeter or more filled in and colorful. And there really wasn’t much for us to do but marvel at its display. I’d hate for anyone to not see it just as it is right now. Pictures don’t do it justice but since the internet prevents me from grabbing you all by the hand to pull you down there, they’ll have to suffice. And if you possibly can carve some time out of your weekend (Sunday is forecast to be the better day) by all means, come see it for yourself. And take a walk by the dove tree on your way. And as you leave, say hey to all the tiny tadpoles keeping warm on the pond rocks.

The Rock Garden highlights for me are an Erigeron glaucus ‘Sea Breeze’ (second picture from the bottom) that has been steadily increasing since we planted it a couple of years ago but I don’t ever remember it blooming before. So pretty! And good old tiarella. Where has this plant (Tiarella ‘Elizabeth Oliver’) been all my life? Suddenly I’m totally in love. We planted these as plugs, also a couple of years ago, and they are really taking off now, each one as pretty as a picture.

What’s going on in your spring tapestry?

Given that March felt like May and April felt a little like July, it’s been really hard not to move everything outside and start planting annuals and tomatoes as if it’s safe. But then didn’t April end on a sort of February-ish note? That was just the warning we needed (I guess) to sit tight in limbo a little longer. According to the National Climatic Data Center, there’s only a 10% chance we’ll see a frost around here after May 6. So the good news is we won’t have to wait much longer.

I think I’m ready to move out just because that’s next on the list of to-dos. For the most part though, the plants don’t seem to be in a huge hurry. They actually look remarkably healthy and unstressed. Sometimes, if we’re really busy in the gardens in the spring, we come back into the greenhouse and are shocked to see that the plants have gone downhill. But this year because we were able to start working outside so much earlier, we have had ample time to pay attention to the greenhouse despite the lack of rainy days like this one to devote to inside work. Add to that the fact that the winter was so mild that the shading never etched off of the glass so the plants have not been subjected to those sunny spring days that can really set the greenhouse cooking. The plants are still just trucking along like they have all winter.

At home it’s a different story. Gail calls this time “the bewitching hour” because one minute our houseplants look fine and the next time we look at them, which could be weeks from that last time because we’re so consumed with our gardens, they’re infested, wilted, dead, or a combination of the three. They’ll be much happier outside with us. That said, tropical houseplants will have to wait even longer for nights to warm into the 50′s.

If it hadn’t rained today (we needed it – again!) we would have planted sweet peas. It already feels late to get them in the ground because we usually plant them the last week in April. Maybe tomorrow. After that we’ll watch the night temperatures and continue the methodical move out of the greenhouse. Marginally hardy plants like phormium and rosemary are out already and have been perfectly fine. But then we didn’t get the frost that some did.

Have you started moving houseplants out yet? Have you been able to resist planting tomatoes?
