Saint Martin Dahlia Tubers - Costco - Longfield Gardens - March 2026

A couple of days ago, I posted the details of the eight-pack of dahlia tubers that I picked up at Costco on a recent visit.  The tubers are from a source that I've purchased many tubers/bulbs from: Longfield Gardens.  And, this eight-pack featured four tubers of two different varieties.  I already posted about the four Rip City dahlias (they're informal decorative dahlias).  Today, I'm posting about the other four:  Saint Martin dahlias.  

I mentioned that these were both new (to me) varieties, but I was drawn to their heights.  My preference is towards shorter varieties that don't have the same staking/support requirements of many other dahlias.  Below is a photo of the back of the package showing the Saint Martin stats.  Note the spacing (20") and height (30").  

And, here below is the front of the package showing the Saint Martin having slightly smaller blooms that are two-toned in white and pink.  

Besides the height, I was drawn to the contrast between the two flowers.  And, how they both seem to 'work' with the dahlias I've been growing in the salmon/yellow/pink tones.  

Here is how Breck's describe Saint Martin:

Every bloom is a one-off with this striking variety, whose 4" flowers are splashed with rose on crisp white petals for a look that’s never quite the same twice. Bred for the cut flower trade, it delivers armloads of long-lasting stems that hold beautifully in a vase. Upright and floriferous, it’s just as suited to borders as bouquets.

Emphasis, mine.  Based on the price ($15 for eight tubers), I'm guessing that these are going to be small, so knowing they're productive is a highlight.  

But, when you look at those photo's, they "give" (as the kids say these days) Waterlily vibes, don't they?  That's what Bluestone Perennials says, too:

Bicolor 4” flowers on tall straight stems are floral designer favorites. Dahlia Saint Martin is a Decorative Dahlia with a waterlily-type form.

I included a waterlily variety in my previous Longfield Gardens tuber order (Creme de Cognac), so we'll have one true Waterlily and this Saint Martin that 'gives' Waterlily dahlia.  

I ran up a total in my last tuber post saying that I needed 21 containers to start the dahlias this year.  With these four new ones, I'm up to 25 one-gallon containers for this year's tubers.  50 total pots?  We're going to need a bigger potting table.
