Check out Mail order perennials a few messages down. I asked the same question last fall.

I ordered a bunch of sale items from them recently. I was disappointed that most of what I ordered was "no longer available" and I didn't know this until I received the box in the mail with only a couple of items. I would not have gone through the expense of paying for the shipping if I had known. I wish they would keep their website up to date.

Look them up in the Dave's Garden website.....there is a Garden Watchdog area. The rating is not particularly good.I have got into the habit of checking there to see what the customer feedback is on any mailorder place that I might be interested in......saves a lot of disappointment.

I think Butterfly Blue scabiosa is quite common. If you can't find it in greenhouses, the cultivar "Misty Butterflies" is quite similar (fairly similar color, same height, etc.)

Or else just try a more reliable mail order company. I'm not sure how Veseys and Dominion seed house rate on Garden Watchdog, but I've ordered from both of them and had good luck.

Beware of Spring Garden. Coincidentally the generic Gardening in Canada forum has a recent thread about them: orders which haven't been fulfilled, busy phone lines, poor customer service. I was one of the lucky ones - part of my order did arrive in good condition, the balance was discontinued and I wasn't charged for an un-delivered product. Others weren't so lucky.

Just got off the phone from Spring Gsrden.....I made the mistake of ordering from them last fall. I finally got my order for irises and daylilies in November! Of course nothing made it. They cashed my cheque in March after invoicing me twenty times for the order I sent the cheque with! Apparently I will be reimbursed the full amount. We'll see if that becomes a reality in August? That's what I was told. Maybe I'll be a lucky one too.
Never any problem with Dominion, McFayden's or Vesey's.
Botanus are excellent to do business with.

As for Scabiosa, I have both Butterfly Blue and Blue Perfecta. Both were bought at Superstore last spring and both are doing very well. $3.99 I believe for a 4" pot.

Scabiosas aren't hard to grow from seed either. I wintersowed some a couple of years ago and they worked great. They are a pretty plant. I think I might have even bought the seed off a McKenzies rack or something like that.

Spring Gardens used to be Rockwood Gardens years ago, let's just say I wouldn't touch the order form with a 10' pole.
