Matthiola ‘Katz White’

Matthiola 'Katz White'

Trial: Annual

Year Trialed: 2007

Good Qualities:

Excellent quality, great scent, very easy to grow; Early blooming; Nothing stood out, we got this in very late, however, when it was getting too warm in the hoophouse; Easy to germinate, fast growing and early to go to field beds; Tallest of series; Great fragrance- we did use the stems in small bouquets and customers appreciated the fragrance; This was a nice white column type stock, but not a noticeably different or improved version of ‘Avalanche’; Good colors, all plants that germinated lived, germinated well.


Not a prolific bloomer, did not transplant well; None; No marketable flowers on any cultivar in series; High proportion of singles; None to speak of, except a little slow.

Similar Cultivars:

This did not seem very different from either the Cheerful series or ‘White Beach’; ‘Avalanche’.


Next time much closer and pull singles (although I used them for mixed bouquets no problem), loved all three colors; All plants in the series looked good during the germination, seedling, and early growth phase as young plants in the greenhouse and as plants in the beds – however, when flowering time came the flowers were useless – one or two florets, stunted spikes and not harvestable; It just doesn’t pay us to grow stock in the greenhouse and then outside it is short and not as nice – we really need to experiment with some hoops in the field to protect the plants and see if we can get larger flowers in the field – my customers would love that; Next time much closer and pull singles (although I used them for mixed bouquets no problem). Loved all three colors; Transplanting into tunnel on day 37 resulted in stockier, taller plants than those transplanted a week later; Would be better in a high tunnel as an early crop.


We did not use any postharvest treatment – plain water; Bleach in water.
