Harbingers of autumn


It may still feel like high summer where we are, but the flowers do not lie. We are on the cusp of autumn.

Colchicum autumnale

Summer here in North Taranaki has not followed its usual pattern. While we are always slower to warm up in November and December than the east coast, it didn’t really feel like summer until mid January. I don’t swim in cold water and I wasn’t tempted into the pool until well into January. Since then, we have been in and out of the water every day in an unseasonably warm and dry spell. A couple of degrees of extra heat on an ongoing basis makes quite a difference when you spend most of your days outdoors in the garden.

A stray belladonna in the raspberry cage was the first autumn bulb I noticed this season

And dry. I know when we talk about dryness, others may scoff. We all adapt to our own, local conditions and we expect rain on a regular basis all through the year. Mark, a keen weather watcher who could have happily pursued a career on meteorology, tells me we only had 40ml in January and that fell basically on one day, late in the month. We don’t ever water the garden (except for some of the vegetables) and we have no irrigation system; it isn’t necessary in our climate and nor does it seem like good practice but we are seeing some floppy looking plants and some early dropping of leaves.

Even the first nerines are opening

When the autumn bulbs started flowering in what still feels like high summer, I assumed they were being triggered by day length, as vireya rhododendrons are. They are certainly not being triggered by change in temperature, either day or night. Mark pointed out that it may well be that one day of rain in January that triggered them into growth and that makes sense because many bulbs are identified as summer rainfall bulbs.

Lilium formasanaum is a bit controversial in this country. It is on the Pest Plants Accord so illegal to propagate or sell. We keep it because it is showy and not a problem in our garden but also, it is not in a situation where it can escape from the garden to become a problem elsewhere.

Zach and I are waiting for rain so we can move plants again. We have plans we want to get underway. At least we know that here, with a temperate, maritime climate, the rains will come. While our high summer may be of short duration, so too is the depth of winter which we measure in weeks, not months. We have exceptionally long autumn and spring seasons and that does make for a good gardening climate.

The autumn bulbs are one of our seasonal highlights.

The Worsleya procera is opening! This bulb is one we take some pride in because it is rare in cultivation, even rarer to see it flowering in a garden situation and it is very choice. It is generally grown as a pot plant in carefully controlled conditions. The lilac colour deepens and spreads as the flower opens.
