Okay, here is a question to generate different opinions:

How many rose seedlings do you have to grow to find a good one?

Depending on the cross, I have estimated about 1 seedling in a hundred is a good seedling, but to get a really good seedling, in my experience, it is closer to about 1 in a thousand.

How do you get that 1 in a thousand?

On average using good parents, I get about 80% take on my crosses. Then, per hip, I get on average about 10 seeds per hip. Then, considering germination, with a good seed parent, I get about a 50% germination rate overall.

So putting that altogether, to get 1,000 seedlings, I need to plant about 2000 seeds. To get 2000 seeds, I need to collect about 200 hips. To get 200 hips, I need to make about **250** crosses.

That is using the above example.

If I use a seed parent that only sets hips 25% of the time, yielding on average 5 seeds per hip and having a germination rate of 15%, I would need to make many more crosses and collect many more hips: It would take 6667 seeds, 1,333 hips and **5333** crosses.

The second example is not an uncommon finding when using a poorer seed parent. Lots of work to produce the same number of seedlings.

How many rose seedlings do you think it takes? How many seeds? How many crosses?
