GBBD 201007: July 2010

Garden Bloggers’ Bloom Day

Carol at May Dreams Gardens invites us to tell her what’s blooming in our gardens on the 15th of each month.

July 15, 2010

Although Austin’s heat index hit triple digit temperatures this week, our actual highs have remained in the 90s. The humidity is smothering. Being in the garden is miserable, even at dawn. If the humidity doesn’t drive me indoors, the mosquitoes do. However, looking at the garden from inside an air-conditioned house, I’m astonished at how green it still is, how lovely it appears from a distance.

I find it interesting to look back at previous years’ GBBD posts. Last July as we kept racking up our triple digit days on the way to 68 (not quite breaking the 1925 record of 69), I couldn’t bring myself to face the garden or to inventory my disappointment. Of course, now I wish I’d made the effort just to see what could bloom in a summer like last year’s. (And yes, a voice in my head told me as much at the time but for once the heart won out.) In July 2008 we were still at the beginning of the drought, suffering but still believing that fall rains would bring relief. The summer of 2007, however, was very similar to this summer.

The rain has encouraged the roses to bloom. All, except ‘Souvenir de la Malmaison’*, have bloomed this month. ‘Red Cascade’ has been the real surprise. It sat there for years doing nothing and this year it’s hasn’t stopped blooming. It wants to be a ground rose though. Long canes snake out hugging the ground. They aren’t happy when I try to tie them up to the fence. The small fig tree I planted last year has doubled in size.

In the losses column another surprise: the gingko tree. It’s never been particularly vibrant but it held on through drought and freeze. It attempted to leaf out this spring, put out a few wan leaves, and then gave up. The rain also killed off my new sotol plant (planted in well draining soil amended with decomposed granite) and my thyme (potted in a deep herb pot).

Rain or drought certain flowers are dependable July bloomers at Zanthan Gardens: Antigonon leptopus, Hibiscus syriacus, Lagerstroemia indica, and Malvaviscus arboreus. Carefree self-sown flowers are Polanisia dodecandra, Ruellia (various), and Rudbeckia hirta. Perversely, given that I always have them, I don’t really want more of them. What I really want this year a Pride of Barbados. I’m almost content to enjoy my neighbor’s as I sit looking out the window from my desk. I could plant my own but when our low temperatures barely drop out of the 80s at night, I’m not highly motivated to work in the garden.

Noticeably absent from the list of dependable summer bloomers are the duranta and the plumbago. Neither has recovered yet from the Great Freeze of January 2010. The oleander is also slowing making its way back and has managed to put out a couple of flowers. I used to it being a huge wall of champagne-colored flowers.

New for July

I’ve tried growing crocosmia several times. This is my first success thanks to passalong plants from AnnieinAustin. They just began blooming yesterday.

2010-07-15. Crocosmia. (Technically this won’t bloom until tomorrow.)

I first noticed the pigeonberry in Eleanor’s Garden of E on the 2009 Master Gardener’s tour. I liked it so much I bought a 4-inch pot of one on the spot. It died back to its roots during the January 2010 freeze and has remained quite small. It began blooming July 10th.

Rivina humilis pigeonberry
2010-07-15. Pigeonberry (Rivina humilis).

When I bought a Mexican buckeye tree a few years back, there were second small plant in the container. I planted it and it’s stayed about a foot tall, smothered under weeds. In late spring when I was cleaning up around the raspberries, I uncovered it. It appreciated either the attention or the rain and has tripled in size in a couple of months. Today I noticed it was flowering, something it’s supposed to do in early spring.

Ungnadia speciosa
2010-07-15. Mexican buckeye (Ungnadia speciosa).

Between GBBDs

Several flower bloomed and faded in my garden between GBBDs and so didn’t show up in the inventory for either June or July. Rainlilies: Zephyranthes grandiflora, Zephyranthes ‘Labuffarosea’ (another passalong from @AnnieinAustin), and the two different white ones. The Crinum bulbispermum rebloomed after the rain.


* 2010-07-18. ‘Souvenir de la Malmaison’ produced one flower. That means every rose has produced at least one flower in July 2010…not all at the same time.
