I have a purple Arum growing in the front garden and up until this year it has flowered every year giving me a beautiful purple bloom every year. This year it flowered and was yellow, then turned to seed. How do I go about saving this seed, as the head is now very heavy and the seeds are still green?
Callas can indeed be grown from seed. Once seed development begins, the flower fades. You will notice the “bumps” on the calyx enlarging; the weight will begin to pull the stem to the ground. This is normal. In time the seed capsules will begin to turn yellow and become mushy to the touch. It appears it's beginning to "rot" but this is all part of the process. At this point, the seed are mature, and each capsule contains at least one or two seeds, each resembling a miniature tuber, about 2 mm in size. Harvesting the seed is a bit messy; just gently squish out the individual seeds. Plant the seed 1/4" deep, space them about 1/2" apart. Cover lightly, and keep them warm, well lit & moist. Germination is erratic, and could take several weeks. Transplant after they've grown two or three leaves. Under optimum growing conditions, you might get a bloom in the second year; otherwise, expect something in the third year.
Arum lilies can sometimes be tricky to get to rebloom. This article will help you (Calla is another name for Arum): https://www.gardeningknowhow.com/ornamental/bulbs/calla-lily/make-calla-lily-bloom.htm
Why is it that the flowers change color? I have a number of colors and I have noticed a nice yellow changes into pink, and sometimes orange. Also, the Picaso color changes from the two-tone to cream or light purple and sometimes almost green. A chocolate color has changed to red. Has anybody else experienced the same or have an explanation for what is happening?
Here is an explanation for why the colored flowers change to green or a streaked green color. Calla lilies are a type of arum lily.
There are also varieties that change color as they mature; This is a varietal trait.
My father brought one of these plants home in the late 1940s. Of course, Mother made him plant it way off in the backyard. I would like to get one for my son as a gift. I live in Oceanside, CA. San Diego County.
Thank you, Joan.
This plant seems to be rare and difficult to track down. Your best bet might be to contact gardening societies and clubs in your area and ask whether anyone has this plant. Or, search on the internet for a bulb from a reputable dealer. They are supposed to be difficult to grow from seed.
