Calendula ‘Maayan’

Trial: Annual

Year Trialed: 2009

Good Qualities:

Great pumpkin color (7); It seemed to be a fairly good producer; Good germination, strong stems and good height; Multiple small blooms on each stem; Lots of cuttable stems, drought tolerant; Shape of flowers were nice; Nice lemon scent; Nice vibrancy, and moderately vigorous plants.

Problems:

Too short (4); Did not last very long in our post harvest testing (2); Just not the kind of flower my customers are looking for, foliage very sticky; Blooms not especially attractive; Don’t think plants got a good start as they were tall going into the field and were maybe stressed, didn’t bloom long into the season, would have liked fuller flowers like shorter calendulas; Branched too much, kind of small; Many had ugly bloom, poor germination, maybe this is not a good choice for our climate; Too weedy for my customers; Fragile and brittle when trying to cut, difficult to know where to cut, outer stems on plant grew horizontal to the ground then curved and grew upright (needed more space and light), this curve was not corrected in a vase, once thinned with first cut the stems grew more upright, on one stem there will be one bloom not opened, one just opened, and one dead, stems got thinner with each cut, and less multiple blooms on a single cut, would take a grower a long time to cut a crop; Flower heads too small, it was more of a spray type calendula; Very poor seed germination for this cultivar – only 23 plants survived to transplant stage; A little bit mildew prone for us near the coast (California).

Similar Cultivars:

Very similar to calendula ‘Princess Yokosuka’ which was planted adjacent to ‘Maayan’, very hard to tell them apart; Reminded me of other calendulas.

Comments:

Calendula is a nice flower but for me, it can only be produced in a greenhouse and it just doesn’t produce enough to make it profitable, it also doesn’t last long enough to make it extremely popular either; I love Calendula but have trouble selling it, even very cheaply in either spring or fall, this year we did not have hardly any aphids or spider mites on the calendula and only did one release of beneficial insects, there were many lacewing eggs spring and fall on calendula, I will continue to plant it for insect habitat, we also have some interest in it for natural fabric dye, grown in high tunnels; Greenhouse grown; This is a super plant, without irrigation it is still blooming; Wish stems were stronger, but did have usable stems; Did not stand out in our trials as anything new or unique; Harvested 6/24-7/3 (planted in field 4/25, Zone 5); Would not grow again; Did not look good with different stages of flowers on a stem; Perhaps it would be better in a dry year.

Postharvest:

Cut early in the day as they seemed to wilt and then come back, kept cool and also used Floralife; No treatment.

See separate postharvest report for results from NC State University postharvest evaluations.
