Pacific Coast Iris
A wonderful small Iris for the dry garden are the 'Pacific Coast Iris'.
These are mainly Iris douglasiana hybrids, an easy care iris grown widely across the United States. However a number of other species are also include in the group, Iris bracteata, Iris chrsophylla, Iris hartwegii, Iris innominata and others.
They are not show stoppers like some of the bigger iris species, but they are a reliable performer in the garden, and they do put on a good show.
These are an iris that take well to being grown in containers as long as you remember to repot them every 2 - 3 years. They need to be in pots that are fairly large for the size of the plant. This avoids the pots overheating, and the soil will not break down as rapidly.
You will also need to water regularly from spring through summer, including a diluted liquid fertilizer in this regime.
In terms of dividing these lovely native orchids, although some growers say divide in fall, we think that early spring is best, this is when new root growth will be occurring, a good time to divide and transplant.
And you will need to divide established clumps every 4 - 5 years to prevent congestion and increase flowering.
They do resent being divided, so try 1/3 of the clump at a time. Replant only the healthy looking divisions, and at this stage give them a little water with a liquid seaweed fertiliser.
