Knockout roses from seed??

I'm just starting to try to grow roses from seed. I would like to pick your brains. I have 2 different roses. One is a Knockout rose and the other is a pink tea rose(name unknown). I plan to collect seeds from both this year. I would love any advice and direction on how to start these. Thank you all for your time. I look forward to your wisdom on this matter.

Link to article below by Dr. Manners on germinating rose seeds.

Your seeds (is your pink rose a "tea" or a "hybrid tea"?) are from hybrids, so your results will vary widely. Only species roses come true to seed. Have fun!

Thanks! That was very informative and to the point. That's just what I was looking for!

RE: Knockout roses from seed??

Dana, Which Knockout rose do you have? I believe that the original Knockout is a triploid and probably will not have viable seeds. But you can certainly use it as a pollen parent. You might want to checkout the Rose Hybridizers Association (RHA) site and do a search on the forum.

Caution, growing roses from seeds, whether they are open pollinated or planned crosses can be very addicting.

RE: Knockout roses from seed??

I have an original knockout rose that I bought quite some years ago. It is the best knockout because the newer two (rainbow and pink) have no scent to speak of whereas the original knockout has a fine tea fragrance. It produces some fertile seed (and lots of large hips) through open pollination (but perhaps with rugosa). I've three or so of this years seedlings from it that have lived. The most vigorous of those has bloomed once earlier this spring and has a bud on it now (not bad for a several month old, one foot seedling). It is a nice single, red with a white center and a buff reverse and strong fragrance. It's quite healthy with more rounded, jagged leaves than the original with red tints.

RE: Knockout roses from seed??

As a followup to my first message. I believe wherein lies the problem is that 'knockout' doesn't produce viable pollen. This means it won't self-pollinate which would explain the relative lack of fertile seeds (and not having to dead-head to produce more flowers). I believe my knockout seedling was pollinated from Rosa Rugosa 'Alba'...which would explain the white color and strong fragrance. Like it's parents, it appears to be quite disease free.
